In 80 Mulard ducks (crossing of Muscovy drakes with Pekin ducks) at 9- and 12-weeks of age the relationships between alive body measurements and live body weight and percentage content of breast and legs muscles, skin with subcutaneous fat, abdominal and intestinal fat and bones in the carcass were determined. According to the multiple regression equations the following parameters are useful for estimating the percentage of meat in 9-and 12-week-old living Mulard ducks: thorax lenght, shank length, breast circumference and breast muscle thickness. The fat content can be estimated on the basis of body weight, arm length, thorax length, sternum crest length and breast depth.
